Anduin, he would treat her to a nice night but would be way too much of a wuss to "pull the trigger".

Pretty much this. There's no other option really. Everyone else is either too old or too violent. Not to mention he's set up to be a bit of a Prince Charming later down the line (unless something breaks him). Unless she's into girls.

Ultimately though it would be her choice. Hypothetically. Which probably means Wrathion, since young women do like bad boys...

Tarenar Sunstrike, that belf from Eastern Plaguelands. He's good looking, not too bright, secretly in love with his dwarf pal so he won't be hitting on her. All her friends (and her enemies) will be jealous.

Knowing my daughter she would probably prefer to be set up with someone dark, brooding and Illidan-like. But she's 13, hopefully she will grow out of that. Hopefully? Please someone give me hope!

Anduin Wrynn. Not only he's underage but I have a strong suspicion he might be gay (his best friends are Velen, Wrathion and that tauren paladin guy and I have never seen him with a girl either), so nothing can happen.

Anduin Wrynn without a doubt.
First, he's calm, polite, wealthy, nice, super wealthy, has a good job, mega wealthy, well he's perfect... and wealthy by the way.
And when the stupid wolf pass away and Anduin takes his rightful place at the top of the Alliance, my daughter will take matters in her own hands like Auntie Onyxia...

Considering he was shaped from stone and all early titan constructs were mass produced. I doubt they need to reproduce, but Throim seems like a respectable lad who keeps asking me to visit him... in the mountains.

Also Baine bro? And you want to criticize me about size of hypothetical dick near hypothetical prom night
